The next 7 days in Santorini

Every number below is the forecast we hold, rendered as text — nothing here is drawn on a canvas or filled in by JavaScript. The rain figure is the highest chance across all 7 days (0%), not the lowest, because the worst number is the useful one.

Booking window Fri 14 Aug–Sun 16 Aug: 9.6/10 for those days alone. The 7-day outlook score (9.7) covers the full table below and includes days outside that window.

How this week got its score

  • 7 forecast days: 6 clear/mainly clear, 1 partly cloudy, 0 overcast, 0 wet (fog/drizzle/rain/showers), 0 stormy.
  • Trimmed mean of day scores 9.8 × 0.55 = 5.41
  • Worst day drag: worst day is 9.3 × 0.25 = 2.33 - one bad day cannot be averaged away.
  • Longest consecutive run of good days (≥7.0) is 7/7 = 100% coverage × 0.20 = 2.00
  • Best single day is 10.0 but it only counts through the trimmed mean - a lone great day cannot carry the window.
  • Advertised 3-day window (2026-08-14→2026-08-16) scores 9.6 on its own.
  • Legacy gate counted 7/7 days as "perfect sun"; this model counts 6 genuinely clear.
